Package: fakeroot
Version: 1.23
On systems where the nofile limit is large, fakeroot hangs
For example on an Arch Linux system, where DefaultLimitNOFILE=infinity
in /etc/systemd/system.conf:
$ ulimit -Hn
1073741816
$ ulimit -Sn
1073741816
$ cat /proc/sys/fs/file-max
18446744073709551615
$ cat /proc/sys/fs/nr_open
1073741816
$ fakeroot /bin/bash
...
Several minutes pass
...
fakeroot shell is presented:
[root@lab1 ~]#
End users do not expect this long delay and kill the process before
then.
The long delay appears to be in this section of faked.c, where
getdtablesize returns 1073741816
