Is /etc/mtab a symlink to /proc/self/mounts ? If so, this mount.nilfs2 (NixOS distro package ?) looks to be wrongly built. There are two version with regards to mount.nilfs2, one uses /etc/mtab and another uses libmount. The latter doesn't rewrite /etc/mtab. The latter version of mount.nilfs2 can be built with "--with-libmount" configure option from the nilfs-utils source package. $ ./configure --with-libmount $ make Regards, Ryusuke Konishi > > I am running NixOS 16.03 > > 'uname -r' gives: > 4.4.14 > > Any ideas? > > Thanks in advance. > > Kind regards, > > Mikael Andersson > -- > To unsubscribe from this list: send the line "unsubscribe linux-nilfs" > in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-nilfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
