[LEDE-DEV] Update to util-linux 2.30.1 breaks x86_64 squashfs-combined

[Philip Prindeville]

Changing the subject from the previous thread as it turned out to not have to do with sysupgrade at all.

What I can tell is this, having added some tracing to fstools.

We get to the call to system() in rootdisk_volume_init():

https://git.lede-project.org/?p=project/fstools.git;a=blob;f=libfstools/rootdisk.c;h=dd00c1b4e5b4aa9b748610fa3e93d301a67101a7;hb=HEAD#l269

and it never seems to return.  The value of “str” is “mkfs.f2fs -q -l rootfs_data /dev/loop0”.

What would cause this to hang rather than return an error?

Thanks,

-Philip
