Hi, please include a description for this. Also, it looks like this is missing the empty_partition() part?

Squashfs, being read-only, is not really useful for a partition that is empty. You wouldn't be able to create files nor actually use it in a meaningful manner, unless it's combined with one of the merging filesystems like {union/au/overlay}fs. In this case the whole fs setup would be described in fstab. Though, it might make sense to raise a warning at least. > > Thanks, > > Tom > > On Wed, 2014-07-23 at 12:37 +0200, Maciej Borzecki wrote: > > Signed-off-by: Maciej Borzecki <maciej.borzecki@open-rnd.pl> > > --- > > .../lib/mic/kickstart/custom_commands/partition.py | 26 ++++++++++++++++++++++ > > 1 file changed, 26 insertions(+) > > > > diff --git a/scripts/lib/mic/kickstart/custom_commands/partition.py b/scripts/lib/mic/kickstart/custom_commands/partition.py > > index d0f1b78..c4d0113 100644 > > --- a/scripts/lib/mic/kickstart/custom_commands/partition.py > > +++ b/scripts/lib/mic/kickstart/custom_commands/partition.py > > @@ -192,6 +192,10 @@ class Wic_PartData(Mic_PartData): > > return self.prepare_rootfs_vfat(cr_workdir, oe_builddir, > > rootfs_dir, native_sysroot, > > pseudo) > > + elif self.fstype.startswith("squashfs"): > > + return self.prepare_rootfs_squashfs(cr_workdir, oe_builddir, > > + rootfs_dir, native_sysroot, > > + pseudo) > > > > def prepare_rootfs_ext(self, cr_workdir, oe_builddir, rootfs_dir, > > native_sysroot, pseudo): > > @@ -324,6 +328,28 @@ class Wic_PartData(Mic_PartData): > > self.set_size(rootfs_size) > > self.set_source_file(rootfs) > > > > + def prepare_rootfs_squashfs(self, cr_workdir, oe_builddir, rootfs_dir, > > + native_sysroot, pseudo): > > + """ > > + Prepare content for a squashfs rootfs partition. > > + """ > > + image_rootfs = rootfs_dir > > + rootfs = "%s/rootfs_%s.%s" % (cr_workdir, self.label ,self.fstype) > > + > > + squashfs_cmd = "mksquashfs %s %s -noappend" % \ > > + (image_rootfs, rootfs) > > + rc, out = exec_native_cmd(pseudo + squashfs_cmd, native_sysroot) > > + > > + # get the rootfs size in the right units for kickstart (Mb) > > + du_cmd = "du -Lbms %s" % rootfs > > + rc, out = exec_cmd(du_cmd) > > + rootfs_size = out.split()[0] > > + > > + self.size = rootfs_size > > + self.source_file = rootfs > > + > > + return 0 > > + > > def prepare_empty_partition(self, cr_workdir, oe_builddir, native_sysroot): > > """ > > Prepare an empty partition. > >
