Sorry, I tried to include pretty much everything. > Also adding -V (for verbose) would give some additional information. Actually, the additional info is very limited (basically, showing the invocation of f2ck.ext4) which is already after is_mounted() has returned the wrong answer, so it wasn't helpful. > 7320: libmount: INIT: library debug mask: 0xffff > 7320: libmount: INIT: library version: 2.27.0 > 7320: libmount: INIT: feature: selinux > 7320: libmount: INIT: feature: assert > 7320: libmount: INIT: feature: debug > Available "LIBMOUNT_DEBUG=<name>[,...]|<mask>" debug masks: > all [0xffff] : info about all subsystems > cache [0x0004] : paths and tags cache > cxt [0x0200] : library context (handler) > diff [0x0400] : mountinfo changes tracking > fs [0x0040] : FS abstraction > help [0x0001] : this help > locks [0x0010] : mtab and utab locking > options [0x0008] : mount options parsing > tab [0x0020] : fstab, mtab, mounninfo routines > update [0x0080] : mtab, utab updates > utils [0x0100] : misc library utils > monitor [0x0800] : mount tables monitor > 7320: libmount: CACHE: [0x9480048]: alloc > fsck from util-linux 2.27.1 > 7320: libmount: TAB: [0x9480068]: alloc > 7320: libmount: TAB: [0x9480068]: /etc/fstab: start parsing [entries=0, > filter=not] > 7320: libmount: TAB: [0x9480068]: add entry: /dev/sda2 / > 7320: libmount: TAB: [0x9480068]: add entry: UUID=[swap device] none > 7320: libmount: TAB: [0x9480068]: add entry: proc /proc > 7320: libmount: TAB: [0x9480068]: add entry: sys /sys > 7320: libmount: TAB: [0x9480068]: add entry: dev /dev > 7320: libmount: TAB: [0x9480068]: add entry: devpts /dev/pts > 7320: libmount: TAB: [0x9480068]: add entry: [network mount redacted] > 7320: libmount: TAB: [0x9480068]: add entry: /dev/sr0 /media/cdrom0 > 7320: libmount: TAB: [0x9480068]: add entry: /dev/mmcblk0p1 /mnt > 7320: libmount: FS: [0x9480b30]: free [refcount=0] > 7320: libmount: TAB: [0x9480068]: /etc/fstab: stop parsing (9 entries) > 7320: libmount: TAB: [0x9480068]: parsing done [filename=/etc/fstab, > rc=0] > 7320: libmount: CACHE: [0x9480048]: canonicalize path /dev/sda2 > 7320: libmount: CACHE: [0x9480048]: add entry [ 1] (path): /dev/sda2: > /dev/sda2 > 7320: libmount: TAB: [0x9480068]: lookup TARGET: '/' > 7320: libmount: TAB: [0x9480130]: alloc > 7320: libmount: TAB: [0x9480130]: mtab parse: ignore mtab > 7320: libmount: TAB: [0x9480130]: mtab parse: #1 read mountinfo > 7320: libmount: TAB: [0x9480130]: /proc/self/mountinfo: start parsing > [entries=0, filter=not] > 7320: libmount: TAB: [0x9480130]: add entry: /dev/root / > 7320: libmount: CACHE: canonicalize path /proc/self/mountinfo > 7320: libmount: TAB: TID for /proc/self/mountinfo is 7320 > 7320: libmount: TAB: [0x9480130]: root FS: 802 > 7320: libmount: CACHE: [0x9480048]: canonicalize path 802 > 7320: libmount: CACHE: [0x9480048]: add entry [ 2] (path): 802: 802 > 7320: libmount: TAB: [0x9480130]: canonical root FS: 802 > This '802' business looks weird.

At first I was worried about spammers address harvesing the BTS and created a separate address so it could be heavily filtered, but then I discovered that spammers tend to filter out e-mail addresses that include the word "spam"! > so I'm closing this bug report. You need to find out what's broken > on your system. Feel free to report back once you find it. I'm trying, but the interface of libmount is a bit obscure. There are comments on all the external functions, but the overall design of the interface and dependencies between the functions are hard to infer. I can see how it *does* work with a debugger, but finding the problem requires inferring how it's *supposed* to work, and that requires more mind-reading.
