[Buildroot] Enable mount SquashFS

[Сергей Сахно]

Good evening everyone. How to enable the ability to mount SquashFS? In the
menuconfig of busybox downloaded from the busybox site there is an item
[SquashFS filesystem] in the [Filesystem / Volume identification] section,
but in the menuconfig of busybox unpacked buildroot it is not.

Busybox CONFIG_FEATURE_VOLUMEID_SQUASHFS depends on VOLUMEID && FEATURE_BLKID_TYPE,
VOLUMEID is already enabled, FEATURE_BLKID_TYPE is Linux System Utilities -->
blkid --> Print Filesystem type

More important is enabled squashfs support in the linux kernel...

Peter

Not much info....why mount to /run/rauc/bundle and not just /mnt ? Why option sizelimit?
Where does the 'installing' error message come from? How is the squashfs image update-last.raucb
created (never worked with rauc (yet))? Loop mounting enabled in the kernel?
Do you run your commands as root user? Which are the file permissions of the squashfs image file?

Regards,
Peter
