changing mount point from /mnt/c to /c

[raymod2]

Years of using MSYS and MSYS2 has ingrained the habit of referring to the C: drive as "/c" but Bash on Windows uses "/mnt/c". A good solution is using a bind mount:

mkdir -p /c
sudo mount -o bind /mnt/c /c

However, this requires root and needs to be run every time you open a bash window. I tried using /etc/fstab for a persistent mount but I couldn't get it to work:

sudo sh -c "echo '/mnt/c /c none bind' >> /etc/fstab

As a workaround you could possibly edit your sudoers file to allow any user to use access mount without root privileges and then add that command to your profile script.

Why not just ln -s /mnt/c /c?
I personally think /mnt/x is a more sane default.

[raymod2]

Yeah a soft link works, too. One minor gripe with a soft link is that "ls /c" doesn't work. You need "ls /c/".

[raymod2]

BTW, this ticket is to look into why /etc/fstab doesn't work.

I imagine this is because WSL doesn't perform most normal Linux systemwide initialization. See #511 , for example.

@raymod2 Here is the solution.

# created as su to match /mnt/c
sudo mkdir -p /c 
# update /etc/fstab; requires su
sudo sh -c "echo '/mnt/c /c none bind' >> /etc/fstab"
# reload fstab; requires su
sudo mount -a

Ticket probably can be closed now.

It's the sudo mount -a that people don't want to run, per what Adam alludes right above. fstab is not respected on WSL instantiation.

It is tempting to dupe these all into #511 ("make systemd work") but now there is precedent in #2530 for adding systemd features to WSL init. I hope that isn't the route this goes, but we'll have to let it play out.

@therealkenc You are correct. I should have posted my answered after testing closing and relaunching a session. Once I noticed I was wrong, I started putting something together to as a work around to share with my team and others.

[sgtoj]

My original solution is the proper linux solution. However, the solution currently does not work for Ubuntu for Windows because mounts are not auto loaded. See @therealkenc comments for more information.

In the meantime, I have documented and posted a short step-by-step guide to implement a workaround.

FYI this is now possible to do it with wsl.conf https://docs.microsoft.com/en-us/windows/wsl/wsl-config
root = /

diego@diego-thinkpad:~$ cat /etc/wsl.conf
# Enable extra metadata options by default
[automount]
enabled = true
root = /
options = "metadata,umask=22,fmask=11"
mountFsTab = false

# Enable DNS – even though these are turned on by default, we’ll specify here just to be explicit.
[network]
generateHosts = true
generateResolvConf = true

diego@diego-thinkpad:~$ mount -l | grep drvfs
C: on /c type drvfs (rw,noatime,uid=1000,gid=1000,umask=22,fmask=11,metadata)
diego@diego-thinkpad:~$

@d1egoaz How to upgrade the latest OS build? The update center gave me " Version 1709, OS build 16299", seems not the one your had mentioned.
