====== 20221024 / upgrade before boot ======

**PSMN boot will take some time**

We are upgrading all backend ($HOME, /Xnfs, services) servers, and it's soooo long...

We **MUST** wait for all $HOME and shared volumes (/Xnfs) to be OK before starting login machines.

Some clusters might startup without scratches firstly...

EDIT 17:30: "le propre des emmerdes, c'est de voler en escadrilles..."

  * one main switch is dead
  * one fileserver is dead (but data are OK, scripts and access paths need to be modified)

planning is delayed...
