change /dev/sdc2 name
hi guys i have a simple question

how can i change /dev/sdc2 to /dev/mhs ??

and how can change eth0 name ??

Why would you want to?? you an add names by tuning udev rules if you NEED to, but I find that very hard to believe. If it's an ext filesystem, just use e2label to set a label on the partition and mount it from that.

Don't fight things unless you have a very good reason. It just makes life much harder.

I don't know if this will get the job done for your needs, but you can always make a symbolic link with your new names to the old established /dev references. You've seen /dev/dvd or /dev/cdrom or something similar. Those are nothing but symbolic links to the actual /dev/sd##. That way you don't have to really change any config, but still have the option of additional reference names for the same device.

I'm with DOSJockey382.

Try to create a symbolic link.

ln -s /dev/sdc2 /dev/mhs
ln -s /dev/eth0 /dev/yourCustomDeviceName

This will keep the original link (/dev/eth0) intact, and avoid any other eventual problem with programs that uses /dev/eth0...

Use Udev rules. It uses device id's to create aliases same as ln but automatically at boot time
Take a look at this. There are some nice examples.

While it is possible to simply create a symlink, many, if not most, distros these days put /dev on a virtual RAM filesystem, and any changes you make will be lost on the next reboot.

The proper way to change a device entry is to use a udev rule. And even then it's generally better to leave the original as-is and tell it to simply create a symlink to it with the name you want.
