Re: squasfs and fetch parameter
Daniele Primon a écrit :
Is the loop device setup correctly? You should try losetup to be
sure. Another hint makes me suspicious about is the double slash in
//fai.squashfs
i rerun with a remade sqaushfs and i got the same problem :
+ mkdir -p //fai.squashfs
+ log_begin_msg Mounting "/live/image/live/fai.squashfs" on
"/fai.squashfs" via "/dev/loop0"
+ [ -x /sbin/usplash_write ]
+ _log_msg Begin: Mounting "/live/image/live/fai.squashfs" on
"/fai.squashfs" via "/dev/loop0" ...
+ [ n = y ]
+ printf Begin: Mounting "/live/image/live/fai.squashfs" on
"/fai.squashfs" via "/dev/loop0" ...
Begin: Mounting "/live/image/live/fai.squashfs" on "/fai.squashfs" via
"/dev/loop0" ... + mount -t squashfs -o ro,noatime /dev/loop0 //fai.squashfs
mount: mounting /dev/loop0 on //fai.squashfs failed: No such device
+ panic Can not mount /dev/loop0 (/live/image/live/fai.squashfs) on
//fai.squashfs
it seems it come from the code in
/usr/share/initramfs-tools/scripts/live ( ligne 1125/1583 ):
mkdir -p "${croot}/${imagename}"
log_begin_msg "Mounting \"${image}\" on
\"${croot}${imagename}\" via \"${backdev}\""
mount -t "${fstype}" -o ro,noatime "${backdev}"
"${croot}/${imagename}" || panic "Can not mount ${backdev} (${image}) on
${croot}/${imagename}" &&
rofsstring="${croot}/${imagename}=${roopt}:${rofsstring}" && rofs$
log_end_msg
this is like if ${croot} was "/" and in fact the code set it to / but
it seems it should not be that ?
here is some debug i was able to do:
-----------------------------------
(initramfs) losetup
/dev/loop0: 0 /live/image/live/fai.squashfs
(initramfs) ls -la /live/image/live/fai.squashfs
-rw-r--r-- 1 0 0 198922240 Jan 27 11:09
/live/image/live/fai.squashfs
(initramfs) ls -la /dev/loop0
brw-rw---- 1 0 0 7, 0 Jan 27 11:07 /dev/loop0
i do not see how ton control why the loop device fails, the loop module
is loaded in the kernel it seems ok
here is the log:
