Elaborating on what rbatte1 already alluded to above: the
man page for
tail (GNU coreutils) 8.25 reads:
Quote:
With --follow (-f), tail defaults to following the file descriptor, which means that even if a tail'ed file is renamed, tail will continue to track its end. This default behavior is not desirable when you really want to track the actual name of the file, not the file descriptor (e.g., log rotation). Use --follow=name in that case. That causes tail to track the named file in a way that accommodates renaming, removal and creation.
Which I guess would exactly solve your problem.

inotail
INOTAIL(1) Inotify enhanced tail INOTAIL(1)
NAME
inotail - A fast and lightweight version of tail using inotify
SYNOPSIS
inotail [OPTION]... [FILE]...
DESCRIPTION
inotail is a replacement for the 'tail' program found in the base installation of every Linux/UNIX system. It makes use of the inotify in-
frastructure in recent versions of the Linux kernel to speed up tailing files in the follow mode (the '-f' option). Standard tail polls the
file every second by default while inotail listens to special events sent by the kernel through the inotify API to determine whether a file
needs to be reread. Note: inotail will not work on systems running a kernel without inotify. To enable inotify, please set CONFIG_INOTIFY=y
in your Linux kernel configuration and recompile it.
Currently inotail is not fully compatible to neither POSIX or GNU tail but might be in the future.
OPTIONS
-c N, --bytes=N
output the last N bytes. If the first character of N is a '+', begin printing with the Nth character from the start of each file.
-f, --follow
keep the file(s) open and print appended data as the file grows
-n N, --lines=N
output the last N lines (default: 10) If the first character of N is a '+', begin printing with the Nth line from the start of each
file.
-v, --verbose
print headers with file names
-h, --help
show help and exit
-V, --version
show inotail version and exit
