If -f argument is a directory add all the files (and only files) it
containes to the config files list.
These files are added in lexical order (man alphasort).
The -f order is still respected:
$ tree rootdir
rootdir
├── root1
├── root2
├── root3
├── superdir1
│ ├── aaa1
│ ├── aaa2
│ ├── aaa3
│ ├── bbb1 -> aaa1
│ └── wrong
│ └── wrongfile
└── superdir2
├── ccc1
└── wronglink -> .
$ ./haproxy -C rootdir -f root2 -f superdir2 \
-f root -f superdir1 -f root1
root2
superdir2/ccc1
root3
superdir1/aaa1
superdir1/aaa2
superdir1/aaa3
superdir1/bbb1
root1
This can be useful on systemd where you can't change the haproxy
commande line options on service reload.
