32 <p>The kernel 2.6 provided by the grml system is based on the latest
33 stable(!) vanilla kernel (taken from <a
34 href="http://kernel.org/">kernel.org</a>) we consider as 'useful and
35 working'. The grml-kernel includes <a href="#patches">several patches</a> and

138 <h3><a name="squashfs"></a>Squashfs</h3>
140 <p>Squashfs is a compressed read-only filesystem for Linux. Squashfs is
141 intended for general read-only filesystem use, for archival use (i.e. in
142 cases where a .tar.gz file may be used), and in constrained block
143 device/memory systems (e.g. embedded systems) where low overhead is
146 Via using the module loop it is possible to mount a filesystem file. squashfs
147 is a "loop" with (de)compression (Compressed Loopback Device) and it is
148 possible to mount a compressed filesystem like a block device and seamlessly
149 decompress its data while accessing it.<br />
151 Whereas Knoppix uses the cloop mechanism, grml is based on the newer
152 mechanism squashfs. The filesystem has been compressed into the file
153 "/GRML/GRML" and is mounted by the initial init process using squashfs.</p>

167 <p>This package contains release specific kernel modules where no extra debian

195 <p>Alternative driver for the Atmel AT76C503A based USB WLAN adapters.
196 Currently, the driver has no promiscous, monitor or station mode and no
197 support for libpcap, i.e. it does not work with Kismet or Airsnort and it
198 cannot act as an WLAN access point. This is a restriction imposed by the
199 current firmware.</p>

216 <p>RAID 1 over TCP/IP for Linux. Drbd is a block device which is designed to
217 build high availability clusters by providing a virtual shared device which
218 keeps disks in nodes synchronised using TCP/IP. This simulates RAID 1 but
219 avoiding the use of uncommon hardware (shared SCSI buses or Fibre Channel).

237 <p>Exmap is a memory analysis tool which allows you to accurately determine

239 libraries on a running system. In particular, it accounts for the sharing of
240 memory and swap between different processes.</p>
242 <p>Notice: exmap isn't shipped by the grml 0.7 Live-CD because it requires
243 too much space. Run 'apt-get update; apt-get install exmap' to install

252 <p> The primary goal of the IvyTV Project is to create a kernel driver for
253 the iTVC15 familiy of MPEG codecs. The iTVC15 family includes the iTVC15
254 (CX24315) and iTVC16 (CX24316). These chips are commonly found on Hauppauge's
255 WinTV PVR-250 and PVR-350 TV capture cards. (Take a look at <a

261 <p>linux-wlan-ng is a set of drivers and utilities that is intended to
262 provide the full range of IEEE 802.11 MAC management capabilities for use in
263 user-mode utilities and scripts. The package currently supports the Intersil
264 802.11b Prism2, Prism2.5, and Prism3 reference designs for PCMCIA, PCI, and
265 USB. Additionally, the package includes support for the PLX9052 based PCI to
266 PCMCIA adapter with a few different PCMCIA cards.</p>
268 <p>Notice: prism2_cs won't work as pcmcia-cs is deprecated and replaced with
269 pcmciautils. The other modules should work though.</p>
273 <p>Using loop-aes with >=2.6.13 fails with 'register_blkdev: cannot get
274 major 7 for loop'. grml requires a stable loopback device interface
275 (CONFIG_BLK_DEV_LOOP=y) but loop-aes has different requirements. So loop-aes
276 is not part of grml.</p>

282 (localfs, sshfs, ftpfs, httpfs, socketfs, freenetfs, and nutellafs)

446 <p>Unionfs is a stackable unification file system, which can appear to merge the
447 contents of several directories (branches), while keeping their physical
448 content separate. Unionfs is useful for unified source tree management,
449 merged contents of split CD-ROM, merged separate software package
450 directories, data grids, and more. Unionfs allows any mix of read-only and
451 read-write branches, as well as insertion and deletion of branches anywhere
452 in the fan-out. To maintain unix semantics, Unionfs handles elimination of
453 duplicates, partial-error conditions, and more.</p>
