Package: coreutils Version: 9.1-1 Severity: normal Dear Maintainer,
If ~/uwu$ echo tupa > t/a/i/l/zupa then $ tail -F ~/uwu/t/a/i/l/zupa tupa and when ~/uwu$ mv t q; mkdir -p t/a/i/l; echo trużpan > t/a/i/l/zupa nothing changes. Naturally, $ cat /proc/$(pgrep tail)/fdinfo/4 pos: 0 flags: 00 mnt_id: 15 ino: 2075 inotify wd:2 ino:20e117 sdev:71 mask:c06 ignored_mask:0 fhandle-bytes:c fhandle-type:1 f_handle:941d177517e1200000000000 inotify wd:1 ino:20e116 sdev:71 mask:784 ignored_mask:0 fhandle-bytes:c fhandle-type:1 f_handle:5d7d142316e1200000000000 and nothing actually changed with what I assume are watches for ~/uwu/t/a/i/l/zupa and ~/uwu/t/a/i/l, and if you muck around with it (by killing q/a/i/l/zupa or whatever) so much tail says it falls back to polling, then it works again. I don't think actually generalising tail -F is possible with linux's (d|i|fs)notify systems. Or that it's worth-while to do so for the specified use-case of log rotation. OTOH, this is NOT documented. And neither is ---disable-inotify, which is needed to work around some Linux bugs (like #1039488). Please (a) document this behaviour, and (b) document ---disable-inotify (for which, funnily enough, the only two results on DCO are coreutils and rust-coreutils: https://codesearch.debian.net/search?q=---disable-inotify&perpkg=1 ) as fixing it.
