Hi! It is, I fear, like in the subject: $ tail -4 /etc/exports.d/zfs.exports /a\040\134053\040b 1(sec=sys,rw,no_subtree_check,mountpoint,crossmnt) /a\040\134134053\040b 2(sec=sys,rw,no_subtree_check,mountpoint,crossmnt) /a\040\134134134053\040b 3(sec=sys,rw,no_subtree_check,mountpoint,crossmnt) /a\040\134134134134053\040b 4(sec=sys,rw,no_subtree_check,mountpoint,crossmnt) # exportfs -ra exportfs: Failed to stat /a + b: No such file or directory exportfs: Failed to stat /a + b: No such file or directory exportfs: Failed to stat /a + b: No such file or directory exportfs: Failed to stat /a + b: No such file or directory I just wanted to export '/a \053 b', of course. The rest are just PoC. The manual states: > You can also specify spaces or other unusual character in the export > name using a backslash followed by the character code as three octal > digits. The this happens on 1:1.3.4-6 off Debian, nfs-utils-2.6.1, and current HEAD (7f8463fe702174bd613df9d308cc899af25ae02e). strace off HEAD attached. Best, наб Please keep me in CC, as I'm not subscribed.
