Startup crash because /proc/stat in inaccessible in Android (accessing boot time required?) #10290
Description
Powershell currently crashes because it's trying to get the computer boot time, which can be unavailable (for example on Android). I don't see having access to the computer boot time being a requirement to launch powershell, this could either record the boot time as unavailable or crash when we actually need that value.
Steps to reproduce
- Setup a Linux distribution on Android (I used Debian 9 on Android 8 arm 64 using UserLAnd)
- Follow the instructions at https://docs.microsoft.com/en-us/powershell/scripting/install/powershell-core-on-arm?view=powershell-6 (I replaced arm32 by
- Run pwsh
Expected behavior
Get a powershell prompt
Actual behavior
FailFast:
Access to the path '/proc/stat' is denied.
