[Trisquel-users] Re : issues with encrypted installation

[lcerf]

/bin/bash is a binary. The GNU Bash shell. 'grub-install' is in '/usr/sbin'  
because it is a non-essential binary used exclusively by the system  
administrator. It can be executed with 'sudo /usr/sbin/grub-install' if  
/usr/sbin in not in the PATH variable.
