/usr wont mount correctly at startup (Permission denied)

Hello everyone ,

I`ve just configured gentoo on my laptop , but I`m facing a problem with the mounting of the /usr partition at startup .
The system boots , but prompts "permission denied" when it tries to fire off software which is located in /usr/bin/ or /usr/sbin/ ...
Stuff as the logger and wpa_supplicant which I use for to manage the WPA2 key exchange wont fire up at startup .

If one were to manually remount the /usr partition - all works well (umount /dev/sda5 ; mount -t ext4 /dev/sda5 /usr) ,
so I`m guessing `tis a problem in the fstab file .

/etc/fstab :

/dev/sda1 /boot ext4 defaults,noauto,noatime 1 2
/dev/sda7 / ext4 noatime 0 1
/dev/sda6 /home ext4 noatime,user 0 0
/dev/sda5 /usr ext4 noatime,user 0 0
/dev/sda2 none swap sw 0 0
/dev/cdrom /mnt/cdrom auto defaults,noauto,user
proc /proc proc defaults 0 0
shm /dev/shm tmpfs nodev,nosuid,noexec 0 0

For example , if one would try to execute "clear" command which is located at /usr/bin/clear
he`d get : "-bash: /usr/bin/clear: Permission denied"
That is if the partitions was not remounted manually after startup .

How should I handle this ?
Thanks ,

Danny .

Permission denied usually happens when exec in not used in mounting the partition try

As g0del pointed out, you need to add exec. The user option is causing it to be mounted noexec
From man page

In general, you should only put the user mount option on filesystems that are noauto and describe removable media such as USB storage devices or optical media.
