** Description changed: In testing use of squashfs images, I found that my initramfs could not mount the squashfs filesystem. Paired with overlayroot, squashfs is very nice for testing. We're investigating use of squashfs as a image type for cloud images. Heres example of the changes to the generated initramfs. Roughly 22k growth on what was ~32M. The only module added is the squashfs module (no additional deps pulled in). $ cd /boot $ sudo cp initrd.img-4.2.0-12-generic initrd.img-4.2.0-12-generic.orig $ sudo dpkg -i initramfs-tools*_amd64.deb - $ dpkg-query -- + $ dpkg-query --show initramfs-tools + 0.120ubuntu6~sm0 $ sudo update-initramfs -u -k 4.2.0-12-generic $ lsinitramfs initrd.img-4.2.0-12-generic.orig | sort > /tmp/list.orig $ lsinitramfs initrd.img-4.2.0-12-generic | sort > /tmp/list $ diff -u /tmp/list.orig /tmp/list --- /tmp/list.orig 2015-10-01 12:59:09.030401257 -0400 +++ /tmp/list 2015-10-01 13:04:56.537463788 -0400 @@ -163,7 +163,7 @@ etc/udev etc/udev/udev.conf init -initrd.img-4.2.0-12-generic.orig +initrd.img-4.2.0-12-generic kernel kernel/x86 kernel/x86/microcode @@ -1461,6 +1461,8 @@ lib/modules/4.2.0-12-generic/kernel/fs/nfs/nfsv4.ko lib/modules/4.2.0-12-generic/kernel/fs/reiserfs lib/modules/4.2.0-12-generic/kernel/fs/reiserfs/reiserfs.ko +lib/modules/4.2.0-12-generic/kernel/fs/squashfs +lib/modules/4.2.0-12-generic/kernel/fs/squashfs/squashfs.ko lib/modules/4.2.0-12-generic/kernel/fs/udf lib/modules/4.2.0-12-generic/kernel/fs/udf/udf.ko lib/modules/4.2.0-12-generic/kernel/fs/xfs $ ls -l initrd.img-4.2.0-12-generic.orig initrd.img-4.2.0-12-generic -rw-r--r-- 1 root root 33555932 Oct 1 13:03 initrd.img-4.2.0-12-generic -rw-r--r-- 1 root root 33533473 Oct 1 12:55 initrd.img-4.2.0-12-generic.orig $ echo $((33555932-33533473)) 22459 $ ls -l /lib/modules/4.2.0-12-generic/kernel/fs/squashfs/squashfs.ko -rw-r--r-- 1 root root 87569 Sep 28 17:27 /lib/modules/4.2.0-12-generic/kernel/fs/squashfs/squashfs.ko - ProblemType: Bug DistroRelease: Ubuntu 15.10 Package: initramfs-tools 0.120ubuntu5 ProcVersionSignature: Ubuntu 4.2.0-10.12-generic 4.2.0 Uname: Linux 4.2.0-10-generic x86_64 ApportVersion: 2.19-0ubuntu1 Architecture: amd64 CurrentDesktop: Unity Date: Thu Oct 1 12:47:13 2015 EcryptfsInUse: Yes InstallationDate: Installed on 2015-07-23 (70 days ago) InstallationMedia: Ubuntu 15.10 "Wily Werewolf" - Alpha amd64 (20150722.1) PackageArchitecture: all SourcePackage: initramfs-tools UpgradeStatus: No upgrade log present (probably fresh install)
