-----------------------+---------------------------
Reporter: kalxas | Owner: kalxas
Type: defect | Status: assigned
Priority: blocker | Milestone: OSGeoLive14.0
Component: OSGeoLive | Keywords: initrd
-----------------------+---------------------------
While remastering the iso, this command
{{{
sudo chroot edit mkinitramfs -c lzma -o /initrd 5.4.0-26-generic
}}}
throws an error
{{{
/usr/share/initramfs-tools/hooks/cryptroot: 64: cannot open /proc/mounts:
No such file
cryptsetup: WARNING: Couldn't determine root device
sed: can't read /proc/cmdline: No such file or directory
grep: /proc/swaps: No such file or directory
/usr/share/initramfs-tools/hooks/cryptroot: 64: cannot open /proc/mounts:
No such file
grep: /proc/cpuinfo: No such file or directory
}}}
resulting into a non bootable inird file.
