  My error not ArchLinux's (see the clip below from the official ARCHLinux wiki

https://wiki.archlinux.org/index.php/arch_filesystem_hierarchy). I am not sure 

where I got the --localstatedir=/run. Not all the info I dig up by using net searches is correct.

I do guarantee that I will double check my info better in the future. I put --localstatedir=/var 

in the PKGBUILD configure even though it defaults to that,  so the info is in front of anyone 

changing the PKGBUILD. 

• 2.12 /run: Ephemeral runtime data
• ..........................cut............
  
• 2.18 /var: Variable files
• 2.18.1 /var/abs
• 2.18.2 /var/cache/pacman/pkg
• 2.18.3 /var/lib: State information

If I can get misinformed so can someone else. Could I suggest that a warning in the configure and/or install docs that

in 4.5 changing from the defaults /var breaks the systemd mounts that xenstore requires?? 

Also quick question if I am understanding my remaining issue [tmpfs: Bad mount option context] as described by a previous thread. Until

the code that generates it changes I need to manually change var-lib-xenstored.mount from

[Unit]

Description=mount xenstore file system Requires=proc-xen.mount After=proc-xen.mount ConditionPathExists=/proc/xen/capabilities RefuseManualStop=true [Mount] Environment=XENSTORED_MOUNT_CTX=none EnvironmentFile=-/etc/default/xenstored What=xenstore Where=/var/lib/xenstored Type=tmpfs Options=mode=755,context="$XENSTORED_MOUNT_CTX"

to

[Unit] Description=mount xenstore file system Requires=proc-xen.mount After=proc-xen.mount ConditionPathExists=/proc/xen/capabilities RefuseManualStop=true [Mount] EnvironmentFile=-/etc/default/xencommons What=xenstore Where=/var/lib/xenstored Type=tmpfs Options=mode=755

Or am I misunderstanding that also??
