[Bug 1308788] [NEW] IMA significantly increases boot time when enabled
Public bug reported:
I have a TPM-enabled laptop (sudo apt-get install trousers tpm-tools &&
sudo tpm_takeownership) and enabled IMA with the following boot options
in GRUB:
"ima_tcb ima_audit=1 ima_appraise_tcb rootflags=i_version
ima_appraise=fix"
As shown from the attached bootcharts, the boot time goes from circa 25s
to circa 225s on an i7, SSD-based system.
