You don't need to do it everytime, just once. The mounted disk keeps
the permisions you set for it. Example with a ext2 floppy:
{root@brian}{/}[150]>umount mnt
{root@brian}{/}[151]>ls -dl mnt
1 drwxr-xr-x 3 root root 1024 Jun 15 18:20 mnt/
{root@brian}{/}[152]>mount -t ext2 /dev/fd0 /mnt
{root@brian}{/}[153]>ls -dl mnt
1 drwxr-xr-x 3 root root 1024 Jun 25 19:45 mnt/
{root@brian}{/}[154]>cd mnt
{root@brian}{/mnt}[155]>ls -al
total 14
1 drwxr-xr-x 3 root root 1024 Jun 25 19:45 ./
1 drwxr-xr-x 33 root root 1024 Jun 15 18:20 ../
12 drwxr-xr-x 2 root root 12288 Jun 25 19:45 lost+found/
{root@brian}{/mnt}[156]>chown root.disk . lost+found/
{root@brian}{/mnt}[157]>ls -al
total 14
1 drwxr-xr-x 3 root disk 1024 Jun 25 19:45 ./
1 drwxr-xr-x 33 root root 1024 Jun 15 18:20 ../
12 drwxr-xr-x 2 root disk 12288 Jun 25 19:45 lost+found/
{root@brian}{/mnt}[158]>cd ..
{root@brian}{/}[159]>ls -dl mnt
1 drwxr-xr-x 3 root disk 1024 Jun 25 19:45 mnt/
{root@brian}{/}[160]>umount /mnt
{root@brian}{/}[161]>ls -dl mnt
1 drwxr-xr-x 3 root root 1024 Jun 15 18:20 mnt/
{root@brian}{/}[162]>mount -t ext2 /dev/fd0 /mnt
{root@brian}{/}[163]>ls -dl mnt
1 drwxr-xr-x 3 root disk 1024 Jun 25 19:45 mnt/
{root@brian}{/}[164]>cd mnt
{root@brian}{/mnt}[165]>ls -al
total 14
1 drwxr-xr-x 3 root disk 1024 Jun 25 19:45 ./
1 drwxr-xr-x 33 root root 1024 Jun 15 18:20 ../
12 drwxr-xr-x 2 root disk 12288 Jun 25 19:45 lost+found/
See the ext2 filesystem on the disk kept the permissions that I gave it.
