Other mounting erofs images in freebsd

[wismos]

there is this erofs image which is a system partition image of an android device that i want to mount under freebsd, i tried doing
mdconfig -f system.img -u 0
mount /dev/md0 /mnt
but that fails with
mount: /dev/md0: No such file or directory
if my memory serves me right, the way to do this on linux was
mount -o loop system.img /mnt

any help would be much appreciated, thanks in advance

What did mdconfig print?

What did mdconfig print?

mdconfig -f system.img -u 0
outputs nothing which gave me the impression that the md device was created successfully which i further verified by running
mdconfig -l
and seeing md0 being listed

sudo file -s /dev/md1?

sudo file -s /dev/md1?

/dev/md0: EROFS filesystem, compat: SB_CHKSUM MTIME, blocksize=12, exslots=0, uuid=4A747088-68D1-3E5B-87BA-D91F35538348, incompat: LZ4_0PADDING BIG_PCLUSTER

Oh I think what FreeBSD means with "no such file" is that it doesn't have an implementation for that filesystem.

Anything at the end of `dmesg`?

nope but i think it is the case of the filesystem not being supported

Is there a fuse filesystem for it?

Is there a fuse filesystem for it?

there is upstream with the name "erofs-fuse" but it seems to not be ported to freebsd yet

Might be more of an issue of interest and not necessarily porting difficulty.

yes, i agree to that, additionally btw there seems to be an userspace linux kernel driver for it, do you think linuxkpi can help?

That's probably a lot of work and if the driver is GPLed it won't make it into FreeBSD. The fuse porting sounds more promising.

thanks a lot for the help and advise
