Recentemente, descobri que minha instalação do debian 8.2 (jessie) está demorando muito para ser inicializada, pois o systemd irá travar por vários minutos em a start job is running for create volatile files and directories . Eu consultei vários fóruns debian que forneceram a solução de excluir o diretório / tmp e recriá-lo.
No entanto, quando tentei fazer isso, recebi o erro: cannot remove /tmp device or resource busy . Já me deparei com outro fórum onde isso é discutido, mas nenhuma de suas soluções está funcionando para mim (lsof e umount).
Como superar "dispositivo ou recurso ocupado"?
Estes são (atualmente) o conteúdo do meu diretório / tmp:
chris@debian:/tmp$ ls -a
. lu7rao5i.tmp
.. orbit-chris
gnucash.trace OSL_PIPE_1000_SingleOfficeIPC_d3a739592b2fd367937df734e849bd3
hsperfdata_chris systemd-private-72f0212651f2433dbce43b96e2dea612-cups.service-9OArRS
kde-chris
Eu fornecerei saída para qualquer comando bash solicitado.

Corrigido! O processo de inicialização foi tão rápido, nem vi a tela de texto!
Eu iniciei no modo de recuperação, digitei a senha do root e fiz:
cd ..
rm -rf /tmp
mkdir /tmp
chmod 1777 /tmp
(O cd .. foi para chegar ao diretório raiz)
Obrigado ao usuário Paul Calabro e outros!
